History & Traditions

Envisioned by its founder as a school rich in music and art, close to the cultural advantages of New York City and embodying “progressive” educational ideas and methods, The Knox School was established in 1904 in Briarcliff Manor, New York by Mary Alice Knox. The School has thrived in four subsequent locations, survived a devastating fire and changed its name from Miss Knox’s School for Girls to The Knox School. Currently situated on Long Island's North Shore, the beautiful and serene Knox campus rests on a small peninsula between Long Island Sound and Stony Brook Harbor, and offers expansive waterfront views. Although continually evolving, Knox maintains many long-standing traditions and is still influenced by the vision of its founder. Today, it is a co-educational boarding and day school for students in grade six through postgraduate, where rigorous academics are combined with athletic and artistic pursuits to prepare young men and women to gain admission to leading colleges and universities.

The Early Years

Mary Alice KnoxMary Alice Knox was born in 1851 into a prominent family of theologians and missionaries. She taught history at Wellesley College from 1887-1895 and then served as principal of The Emma Willard School from 1897-1901 where she developed much of the educational philosophy that influenced her 1911-1912 vision for her school for girls. Unfortunately, her tenure at Knox was short-lived. One Saturday afternoon in 1911, while returning from a matinee performance at the Metropolitan Opera with students and faculty, there was a train accident that killed several of her pupils. Though unharmed herself, the shock appeared to be too great for Mary Alice, and her passing followed soon thereafter. Her tragic loss threw the school into a state of shock; but fortunately, leadership was immediately assumed by Louise Phillips, whose brother, Frank Phillips, was one of the trustee-owners. A distant relative of the founders of Phillips Exeter Academy and an 1891 graduate of Smith College, Mrs. Houghton had been a private school teacher since the death of her husband in 1905. She was, therefore, prepared to assume the responsibilities of her new role as Principal.

1912 - 1920

Knox took a bold leap of faith in 1912 and rented larger quarters for the forty-two girls enrolled that fall. The new campus, located in Brookside Park in Tarrytown, New York, was a sprawling physical plant (whose buildings bore the names of roses) with ample room for the School to grow, and grow it did for the next eight years. The world was reverberating under the impact of World War I, and although “Knoxies” were certainly involved in the war effort, the daily schedule took little notice of world conditions. Three times each day pupils lined up awaiting a faculty member to lead them to meals. Morning assembly was followed by classes at nine, a bread-and-milk snack at mid-morning, a chaperoned walk around the grounds, athletics, Senior Tea with Mrs. Houghton, supervised study hall, and an after-dinner songfest followed by early bedtime.

The Knox School

Opening day, October 4, 1920 found the 36 faculty and 158 girls of The Knox School in awe of the grandeur of the School’s new home on the shores of Lake Otsego in Cooperstown, New York. For the next thirty-four years, the Otesaga Hotel would be the School’s home from October through May of each year. Traditions were cherished in Cooperstown, while practices such as calisthenics in the open air at 7:30 a.m. were often a source of irritation for Knox girls. Yet, there was also a good deal of fun to be had and the run-on grace from Mrs. Houghton “lordblessthisfoodtoouruseandustothyserviceforChrist’ssakeamen” was a source of guaranteed giggles at evening meals.

1930 - 1954

During the depths of the Great Depression and World War II, the Principal and Assistant Principal met the challenges hurled upon them by the outside world. While 300 Knox alumni were active in the war effort, students prepared for the Winter Carnival; performed in horse shows; enthusiastically sang class songs during the Lantern Parade; avidly competed in the yearly song contests that produced “Knox is Filled with Passing People”, written by Margaret Henderson in 1927 and the “Senior Spring Song” by Linda Mosher 1944. Senior Blazers were first worn in 1931 and were changed to white in 1943. A gold and carnelian Senior Ring was adopted in 1933 and Rose (1945) and White (1947) Team Songs were made permanent. Suffering from failing health, Mrs. Houghton retired in 1948 with the title of Principal Emerita, turning the School over to Mrs. Phinney (A.B. Smith, A.M. Columbia). Over the next six years, cessation of railroad service to Cooperstown and rising heating costs, along with restrictions on the school year by the owners of the Otesaga Hotel, caused the Bursar, Ethel Knipe, to convince Mrs. Phinney and the Board of Trustees to find a permanent campus for The Knox School in Nissequogue, Long Island, the highlight of 1954, the School’s 50th anniversary.

1954 - 1971

The new campus was a sixty acre estate known as “Land of Clover” (which had been passed from Lathrop Brown to the LaRosa family, who owned LaRosa Spaghetti company) on Long Island’s prestigious North Shore. It included a thirty-five room Georgian mansion modeled after Westover Plantation in Williamsburg, Virginia by the eminent architect, Archibald Brown; a distinctive barn and riding facilities; access to horse riding trails and close proximity to New York City. In a curious twist of fate, Mrs. Houghton’s funeral coincided with Opening Day for the new campus in the fall of 1954. Much had to be done to convert the estate into classrooms, dormitories and a gym, but Mrs. Phinney who was now 75 years old found her age to be no obstacle.

1971 – 1975

The School’s survival was very much in question when the Board of Trustees pinned their hopes on a young man ready for the challenge in the spring of 1971. Clifford Kapps Eriksen (B.A. William and Mary, M.A.L.S. Wesleyan) became Knox’s first Headmaster. With more than twenty-five years of New England prep school experience, he along with his wife Elsa brought to Knox the qualities of energy, commitment and vision. Mr. Eriksen returned to the structure and traditions of Knox’s former years, expanded the academic program and restored traditions that had been discarded in the late sixties. In addition, the lower school was reactivated and recruitment extended to the four corners of the globe; but in September of 1973, the most dramatic step was taken, six boys were admitted to the School. When the School opened for its 75th year in 1978, enrollment had risen to over 140 students with an equal number of boys and girls. Special recognition was given to Miss Wood in the spring of 1978 on the occasion of her 50-year association with Knox, but Mrs. Phinney did not live to see the School fully recovered. Her passing at the age of ninety-five in 1975 brought an era to a close, and strangely enough, her funeral, like Mrs. Houghton’s twenty-one years earlier was on Opening Day.


1975 - 1994

A Diamond Jubilee Reunion was held on Cooperstown in May of 1975, and in the years that followed, the School entered a period of unprecedented growth. An exchange program with Bedstone College in Shropshire, England was established in 1982 and Knox reached its highest enrollment (180) on the Nissequogue campus. Full accreditation was granted to the School in 1983 by the Middle States Association of Colleges and Secondary Schools, and the School’s first fully-funded scholarship was established in 1987 in memory of Allen Manfuso ’83. Equally important to the School’s growth were construction projects completed between 1979 and 1993: MacKenzie House (honoring Trustee Ian MacKenzie) in 1980, the Elaine and John Steinbeck Media Center (1980), an art studio (1982), music classrooms in Bancroft-Phinney Gymnasium (1983), two faculty houses (1984), expansions to Upper Dorm and Senior Cottage (1985), Miura Hall boy’s dormitory with adjoining faculty housing along with the completion and the dedication of the Wm. Turner Shoemaker Theater (a tribute to Knox’s longtime drama director, mathematics chair, and chaplain) in 1987. In 1989, Lawrence Hall, a mathematics/sciences building honoring Trustee A. Brewster Lawrence was built and in 1990 the Joan Plimpton Mackinnon Library Wing was completed. During the 1980’s numerous sports were added to the School’s athletic program and athletic facilities were expanded adding a baseball diamond (1980), four tennis courts (1985), and a new riding ring (1988).



The ten years leading up to the School’s centennial, represented a period of evaluation and evolution. Fine and performing arts continued to flourish, the riding program housed in the Phebe T. Phillips Equestrian Center remained strong and the School continued to take advantage of cultural offerings in New York City with frequent trips to the symphony, ballet, opera, Broadway theaters, museums and art galleries. When Clifford Eriksen stepped down in 2000, Assistant Headmaster Michael Esten was appointed Head of School. During his tenure, Michael Esten (BA Boston University, MBA LIU/C.W. Post) oversaw vital changes in the School as it prepared to meet the demands of education in the 21st century. He strove to raise the faculty’s awareness of the need for professional development, stepped up constituent outreach, initiated the School’s student advisor program, championed improvements in the academic curriculum, and created more distinction between grade levels. Upon Mr. Esten’s departure in 2002, F. Graham Brown was named Interim Head of School, and then Head of School the following year. He came to Knox out of retirement after sixteen years as Head of School at three different K-12 schools. Mr. Brown immediately set upon a course to invigorate the school, working with the Board of Trustees to develop a strategic plan, “Preparing the Next Generation.” Central to this plan was a revised Mission, Purpose and Philosophy and Core Values that permeate all aspects of School life. Under Mr. Brown, a sixth grade was added along with a more clearly defined Middle and Upper School, a summer camp was established, a Parents’ Association was begun and a major capital campaign to fund critical improvements and upgrades was launched.


2004 - Present

In the fall of 2004, Mr. Brown announced his intention to re-retire. Shortly thereafter, David B. Stephens (B.S. Hobart College, M.S. Syracuse University) was appointed Head of School. When David Stephens began his work in the summer of 2005, he brought to Knox a strong background in independent school education and a love of School history and traditions. Dedicated to academic excellence, he worked with his administration to restructure the academic program. Under his guidance, the lower level of Bancroft Phinney Hall had a major renovation adding locker rooms, offices and classrooms, such as the E. Janice Zingale Music Room. Other facilities on campus received cosmetic improvements and a gallery was created in the Houghton Solarium to show the work of Knox students and visiting artists from the community. In 2008, Mr. Stephens left Knox and George K. Allison (A.B. Union College, M.A. Trinity College), who was Assistant Headmaster under Clifford Eriksen from 1976 –1985, returned as Headmaster, postponing the retirement he and his wife Lucy had planned after George’s twenty-three extremely successful years as Headmaster of Perkiomen School in Pennyslvania. George Allison’s love for Knox was evident from the moment he stepped back onto the campus. He immediately set to work improving facilities, updating technology and installing computers and Promethean ActivBoards in all classrooms; as well as re-energizing the Offices of Admissions, Development and Alumni Affairs. In addition, he strengthened a faltering Parents’ Association holding regular meetings in his home. Also through his initiative, the “Semper ad Lucem” Chapter of the National Honor Society was established at Knox. George Allison’s involvement in the local community, his standing in the independent school profession and his participation in various conferences around the world are helping to raise awareness of Knox. In addition, his continual outreach to alumni, parents and friends has begun to yield positive results, such as the Knipe Cottage expansion, scheduled for completion in August of 2011 that will make it possible to house twenty-four additional girls and three faculty families. Also, the School is waiting for final approval from the town and village for the building of a seventy-foot “catwalk” into Stony Brook Harbor to support our camp program and Knox Crew. Many long-time Board members have been transitioning off of the Board of Trustees, enabling the Board of Trustees and Mr. Allison to fill these vacancies with alumni of the School. In accepting the position of Headmaster, George Allison’s goal was to “right the Good Ship Knox”, preserving the best of the past and guiding the School toward its considerable potential in the second decade of the 21st Century. He is making notable progress in all areas as he continues to lead Knox “Always toward the Light.”
